GTAW is a novel process where a tungsten filament is superheated in an inert gas atmosphere (typically localized) to the point that the input energy exceed the gases ionization energy. This results in a plasma arc that is leveraged to locally melt base materials. Filler material is typically applied to add alloying elements and assist in achieving coalescence of substrates.
GTAW can also be completed in an atmosphere-controlled environment. This typically takes the form of a glove box, environment chamber, or plastic bubble. These atmosphere-controlled environments are ideal for aerospace materials such as Titanium, Niobium, and Nickel based alloys. While atmosphere-controlled environments offer superior material properties, a high degree of skill is required to work in these environments due to restricted movement of welder’s arms and limited line of sight.
